AUTOMOBILE SEAT.

Specification of Beissued Letters Patent.

Original 'No. 1,879,270, dated May 24, 1921, Serial No. 382,508, flled'lliarch 1, 1920. Application fol-reiasue filed September 27,

To all whom it may concern:

'Be it known that I, JAMES H. MoCoL- LOUGH, Jr., a citizen of the United States, residing at San Jose, in the county of Santa Claraand State of California, have invented certain new and useful Improvements in Automobile Seats, of which the following is a My invention relates to mob1le seats.

These seats, as ordinarily constructed, are upholstered with resilient cushions mounted upon a solid or fixed frame, the shocks or vibrations bein absorbed by the springs of the cushions. Tominim ize these shocks or vibrations as much as possible, care is taken to provide not only the bottom cushion with but also to furnish the back cushion wit such easy springs also, thereby recognizing that the shocks reach the occupant of the seat through both cushions. But while the human body is able the class of autoto sustain with minimumdiscomfort and injury the relatively vertically directed shocks such as are transmitted through the bottom cushion, it is not adapted as well for sustaining the shocks transmitted through the back cushion, the effect of these latter shocks being comparable {to that which would be produced if while one is seated in a chair, another should grasp him by the shoulders and forcibl shake him back and forth. It, therefore, appens that due to these back shocks, transmltted through the back cushion, there results a condition-of fatigue,

' principally in the muscles of the shoulders ,and neck, since these parts are subjected to the most continuous strain.

Theobject of my invention is to provide an automobile seat which while adapted for the use of the most luxurious and approved upholstered cushions, is ca able of practi cally eliminating the shoe which would otherwise reach the occupant through the back cushion.

To this end'my invention consists in the novel automobile-seat which I shall hereinafter fully describe, by reference to the ac-, companying drawing in which one form of my invention is illustrated, though it will be understood that changes in form and arrangement may be had without affecting the essential nature and effect of the invention as defined ,by the appended claims,

In the illustration of the seat as here given which indicates a practia fragmentary portion of the cable though not an essential arrangement and form, there is a fixed frame composed of a bottom portion 4 and a back portion 5, supported from the floor .of the automobile by the uprights 6. There is also a second frame similarly composed of a bottom portion 7 and a back portion 8, the two port1ons forming a rigid L-shaped frame. The second frame is nested within but spaced from th fixed frame.

automobile, 2 its floor and 3 its cushion, the form of cushions here shown be- 1 ing the usual type of spring cushions, the springs being indicated by 11. These cushlons are carried by the second frame, but, in

order to conform to customary general style and appearance the upholstery of the back cushlon 10, as shown at 10, is carried over and free of the top edge of the back portion of the second frame and is attached to the top edge of the back portion of the fixed frame, thus inclosin'g and concealing the second frame.

The second frame is connected with the fixed frame preferably though not necessarily at the forward edge of the bottom portrons ofboth by a horizontally directed yeldable' joint, which in its best form is a affording some support to, the second frame, to still yield in its bight under the inde ndent movements of said frame. yielding or hinge movement though slight 1s sufficient for the purpose. Between the two frames and controlling the relative movement of the second frame is a resilient member, here shown as a spring 13. In its best position it lies between the two bottom portions of the frames, as shown, as in this position it may be of effective strength and yet sensitive to the lon leverage of the back portion of the second game.

It will now be seen that the shocks and vibrations transmitted through the fixed frame will be almost wholly absorbed by the sprin 13, the second frame being capable of yiel ing as a rigid unit about its hinge conneccon- This orm of and vibrations of the fixed frame will produce practically nothing but vertical movements of the second frame, very much lessened in, intensity, and as hereinbefore stated this conversion of direction will; result in avoiding the fatigue occasioned by occupying the seat for a long time while the vehicle is in motion.

1. An automobile seat, comprising afixed frame with bottom and back; a second framewith bottom and back nested in and spaced from the fixed frame; a bendable U'strap connection between the forward edges of the two frames forming a horizontally dispose yielding joint therebetween; and a resilient member between said frames rearwardly of said connection.

2. An automobile seat, comprising a fixed.

frame with bottom and back; a second frame with bottom and back nested in and spaced from the fixed frame; a bendable U-strap connection between the forward edges of the two frames forming a horizontally disposed ielding joint therebetween; and a resilient member between the bottoms of said frames. r

3. An automobile seat comprising a fixed frame with bottom and back; a second frame, with bottom and back nested in and frame, the back of spaced from the fixed said second frame terminating below the upper-edge of the back of the fixed frame; a

horizontally disposed joint connection between the forward edges of the two frames; a resilient member between the'two frames rearwardly of thehinge connection; a seat cushion carried by the bottom of the second frame; a back cushion having its covering extending continuously from the loweredge of the back of the second frame to'the top of the back of the fixed frame, said covering being spaced from the upper edge of the back of said second frame; and cushion rearwardly of mg extending over the name to this specification.

4. An automobile seat comprising a fixed bottom and back; a rigid L-sha'ped seat frame nested in and spaced from the fixed bottom and back; a connection between the bottom of the seat frame and the fixed bottom adapting the seat frame for oscillation about a horizontal axis; means for limiting the extent of said oscillation; a seat cushion carried by the bottom of the seat-frame, and a back cushion having its covering extending from the lower part of the back to the seat-frame over the top thereof and secured to the fixed bac 5.
